Interesting news here - see Q21 and Q142 in particular. It looks as if the junction mods at Smallbrook mentioned in an older thread (38TS) are off the agenda though (Q125) (Sorry if this is the wrong section to post in - it seemed the closest fit).

It's on Page 2 or 3 I think. SWT are looking to use the Piccadilly Line stock when it comes to replace their Island Line trains. Someone suggested they purchase new stock as part of a TFL order like with the 92TS.
As an aside some of the complaints on there are so pathetic in their attempts at offending SWT or their staff that I can't believe people put their real names to them. It's mainly about the stock they are using on the Portsmouth fast services.

I heard a 'rumour' last week that the Piccadilly Line replacement stock will be designed, together with new signalling, to run in-and-out of depots/sidings without a driver* (i.e. unstaffed). Presumably this would remove the need for operational LU staff to even enter such areas ever again, aside perhaps for training. This would bring about a huge increase in T/OP productivity I guess and substational reduction in overall numbers. The next step would be the removal of drivers from all trains running in open sections, with staff only retained in tunnel areas; and with a 'target' of 2020 set for this! All just pie-in-the-sky or another case of middle managers carrying out unauthorised 'blue skies thinking'?
* The 73TS have an unused "PROG" position on the reverser barrell to faciltate the same thing.

[head over parapet] Unmanned reversing is done in places like Hong Kong and Bangkok and I don't see anything wrong with it technically or operationally. However, unmanned depot operations are fraught with obstacles unless the place has been specially built for it and it's not cheap to convert to it. The staffing issues are a whole 'nother ball game.[/head over parapet]

How is unmanned reversing carried out. Does the T/OP just park in a reception siding, select auto park on a control panel, exit the train then press some button on a trackside panel to say he's clear then the electronics do the rest to drive the train to it's parking position in the depot.

Just reading that, there are some really stupid questions there, and some pretty sarcastic/unhelpful answers from SWT:
Question: 32 Why is there a gap between the train and the platform edge? Posted by Alexander Read 25/02/2010 08:58:00 Answer: There has to be a gap between the train and the platform edge to prevent trains from hitting the side of the platform.

I don't see the problem here. The standard of answer exactly matches the standard of question (as in the old adage "ask a stupid question and you'll get a stupid answer").

The Bangkok system (Skytrain) allows the driver to stay on the train or get off. IIRC, if he stays on, the driver arrives at the terminus, tips out, closes the doors, switches to auto reverse, removes his key and walks through the train as it goes into a reversing siding beyond the terminus (like Colindale, Wood Green, Marble Arch). It reverses itself and then drives itself out into the departure platform. By this time, the driver has reached the other end, inserts key, switches to ATO and opens the doors. If he wants to get off, he goes through the same process but after closing the passenger doors, he removes his key, gets off, shuts the cab door, inserts his key into a platform switch, sets the auto reverse, removes the key and then goes to make tea etc. He has to be quick because a 3-car train does the whole shunt (wheel start to wheel stop) in 90s.

Fascinating. I wonder if there are any Youtube vids of this operation.

A tradition going back to Victorian times! Question to the civil engineer of the Settle & Carlisle line: "Sir, why is Dent station four miles from Dent village?" to which the answer was "So as to be immediately adjacent to the railway tracks."

You don't have to travel as far as Hong Kong, unmanned reversing is actually used in Vienna, Austria. The driver gets out, shuts the cab door and inserts a key in a yellow box at the platform end. Then he makes sure that all passengers have left the train, presses a button and the train doors close. Finally he presses another button and the train leaves the platform, goes onto the reversing siding, changes direction, comes back to the other platform, stops at the platform beginning in order to let the driver enter without having to walk the entire length of the platform, and then continues to the end of the platform. Upon arrival the driver opens the doors and regains control over the train.
P.S.: By following the link, you can see a train driving to the platform by itself and letting the driver enter:
P.S.2: Another video, showing the entire process (the driver chose to close the doors from the cab):
P.S.3: One more, this time showing a new train:
